Has anyone heard of this? Apparently it is rather rare - even within the gifted populace.

nobody has anything on this for me??

Never heard of it, sorry. Context? Something to do with dual process theory?

Yes ColinsMum, that is the basis of it.

Context:
In the reports we got from both my older boys tests, the psychologist mentioned that they are both true dual processors - they can focus equally and at a level well above "competent" on two totally unrelated tasks at the same time.

I finally saw this happen with my middle son and it was quite incredible to watch. She mentioned that it is very rare to find people who can properly dual process. I managed to get two kids that can - and I found out two friends have children who are also confirmed as dual processors...
